The resistance contribution from the traces between input series resistors and the shunt resistor is dwarfed by the mismatch between R1 and R2 just due to their tolerance. So, DC offset introduced by the input bias is solely due to R1-R2 imbalance. DC…
Test and measurement equipment such as oscilloscopes and waveform generators has its own set of design challenges, from increasing measurement accuracy to providing a low-cost solution to the customer. Measurement accuracy, bandwidth and throughput …
Other Parts Discussed in Post: AMC1200 , AMC1301 , ADS131A04 Protection relays are used to protect high- or mid- or low-voltage power systems, sense an abnormal condition in the circuit, and command the operation of circuit breakers. Voltage and current…
